and dark (ventral) pigmentation of the cepha- 
lothorax. The small size and the length of 
trumpets will normally separate this species 
from all other mosquitoes in the held. 
The adults of U. barnesi have been collected 
in nature resting on tree buttresses in the 
jungle as well as hying in shaded situations. 
Both males and females have been collected 
occasionally in hand night catches but never 
actually biting. They are moderately attracted 
to lights at night.
